With the managed care movement of the 1980s and 1990s, insurance companies cut costs and reduced what services they’d pay for. They required that patients give up their longtime physicians for those on a list of approved providers. They negotiated lower fees with doctors. To make up the difference, primary care docs had to fit more patients into a day. (A Newsweek story claimed that to do a good job a primary care doctor ought to have a roster of eighteen hundred patients. The average load today is twenty-three hundred, with some seeing up to three thousand.)
